Resolved questionsWhat's the meaning of "pass" here?

The last week we were in New Jersey, Sterling came to see us in our room. We were packing up all of our gear that we knew we wouldn’t need. The higher-ups had told us we’d have a pass soon and that our families would be able to see us for a last visit before our battalion’s movement. The only thing left was a final range day, put in place as the result of a suggestion Sergeant Sterling had passed up the chain of command. What's the meaning of "pass" here?Thanks!
